This complex case stems from May 2014 when the then-12-year-old girls allegedly stabbed their friend 19 times to please the internet horror character Slender Man. Both Morgan Geyser and Anissa Weier are 15 years old now. They've pleaded not guilty in adult court to attempted homicide charges by reason of mental disease.

Geyser is growing up in institutions, including the prison system. She has been diagnosed with early onset schizophrenia. On Monday, Geyser's attorneys asked that her confession be thrown out, and that the trial be held in a county other than Waukesha due to all the publicity. They also asked that the girls have separate trials.
